Intelligent Building (IoT)• Occupancy Volume (mass)• Load Control

– Wiring devices– AC circuit relays

• Temperature• Humidity• Gasses

• Circuit Monitoring– Electricity consumption– Demand responses

• Motor Control– Shades

• Locating– Wayfaring– Beaconing

• On the horizon– LiFi

Modular Plug Terminated Link (MTLP)

• Standards legitimize a common practice– ANSI/TIA 568.2-D– ANSI/BICSI 007-2017

• Not always the best / economical solution

Zone Cabling

1. Install Horizontal Cabling early in the construction and leave the job.– Easier to install without ceiling grid, etc.

2. Return for easy finish work. Install lights with patch cords.
